WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,050, dated December22, 1885,

Application filed April 4, 1885. Serial No. 161,237. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM ARNOLD, of Pawtucket, in the county ofProvidence and State of Rhode Island, have invented an Improvement inWashing-Machines, of which the following is a specification.

My invention relates to an improvement upon the invention described inmy Letters Patent No. 120.809, dated November 14, 1871;

and it consists in the combination therewith of a safety pipe, ashereinafter fully set forth.

Figure l is a vertical section of the washing-machine and boilerprovided with my improvement. Fig. 2 is a side elevation of the same.

In the accompanying drawings, A is the square box of an' ordinarywashing-machine, resting upon the legs a.

B is a dasher which is rotated by means of the crank C and bevel-gears DD, or by other suitable means, the dasher, crank, and gears beingoperatively attached to the hinged cover E of the box.

F is a cylindrical boiler or heater attached to the cross-girts b b bymeans of the straps c 0. The boiler F has an outer shell, d, and aninner shell, e, forming between them the annular water-space f, which isconnected to the chamber J of the box A by means of the pipes G, H, andI. The pipe G, being made shorter than either of the pipes H or I,extends direct from the higher portion of the boiler to the perforatedbottom of the box A, whereas the pipe H is made to extend downward fromthe bottom of the box and to connect with the boiler at a point lowerthan the lower end of the pipe G, in order that the cooler Water fromthe chamber J of the machine may flow downward through the pipeH intothe boiler, the heated water and steam from the boiler at the same timepassing into the chamber J through the comparatively short pipe G.

The cylindrical space g is the fire-chamber. h is the door of the same,and 15 is the smoke-pipe through which the products of combustion escapeto the chimney or to the open air.

In washing-machines constructed under my former patent, in which theboiler F is connected to the bottom of the box by means of the pipes Gand H alone, it has been found that there is great liability of havingthe clothes that are being washed in the chamber 5 J drawn by thedownward current over the upper end of the pipe H, so as to prevent thewater from flowing into the boiler, and upon such stoppage the heat ofthe fire will cause the gradual expulsion of the water from the boiler,in which case the comparatively thin material of the boiler will bequickly destroyed by the heat; and heretofore it has required constantcare and supervision to avoid this liability; and the object of mypressmaller diameter than the pipe H, which is connected at the side ofthe box A, instead of its bottom, and enters the chamber J near thewater-line, and also connect the said safetypipe with the boiler at apoint as low or lower than that of the pipe H, so that in case the pipeH is at any time obstructed the safetypipe at the side of the box andnear the waterline will be free from obstruction, and still continue tosupply water to the boiler, thus preventing injury to the same from lackof attention, as heretofore.

The operation of the machine is as follows:

Water should be poured into the chamber J in sufficient quantity to fillthe boiler F and the chamber J to a line above the orificej of the pipeI. A wood fire may then be built within the chamber 9, and when thewater commences to boil it will rise through the pipe G into thewashing-chamber J, and the cooler water will pass from the chamber J 0down the pipe H to keep up a perfect circulation. While the hot water isthus circulating through the clothes in the machine they are also to beacted upon by the revolving dasher B, which will operate to clean the 5clothes very expeditiously; and when the operator is called away fromthe machine, so that the clothes will be allowed to settle 5 In awashing-machine, the combination of down over the orifice of the pipe H,the safety-pipe I, all arranged and operating sub smaller safety-pipe Iwill operate to convey stantially as described. water in proper quantityto the boiler.

I claim as my invention- WVILLIAM ARNOLD Witnesses:

Correction in Letters Patent No. 333,050.

It is hereby certified that Letters Patent No. 333,050, granted December22, 18815,

upon the application of William Arnold, of Pawtucket, Rhode Island, foran improvement in Washing Machines, was erroneously issued to Raymond N.Oolvin, of

Providence, Rhode Island, as assignee of the the entire interest in saidinvention;

that said Letters Patent should have been issued to William Arnold, ofPawtacket, and

Raymond N. Calvin, of Providence, Rhode Island, said Oolvin beingassignee of onehalf interest only; and that said Letters Patent shouldbe read with this correction therein that the same may conform to therecord of the case in the Patent Oflice.

Signed, countersigned, and sealed this 15th day of June, A. D. 1886.
